I’ve been connecting to my Gen 5kW Hybrid over Ethernet > Router - 100mps Switch - Inverter.
Today, I changed the switch to a 1000mps device. I didn’t turn anything off, just unplugged, located the new switch, tidied up the cables and then turned the new switch on.
Other devices on the switch are a camera NVR, a weather station, and another switch supporting another NVR an ESP32 device and a WiFi extender.
All these other devices fired up OK and reconnected but the Inverter did not!
It refuses to connect even after several off and ons, and a reset of the router too.
The light on the RJ45 socket flashes on about once a second whilst all the others are on permanently but flickering.
It has a Reserved IP from the router but is not showing up in its list of wired devices. It does not reply to a ping.
My phone is showing the Inverter’s AP SSID but it won’t connect to it.
Any ideas?
Probably having issues with the auto-negotiation at 1Gbps. Is the switch a managed one so that you can enforce a maximum of 100Mbps on the port used for the inverter connection? Either that or put the 100 Mbps switch back in the leg to the inverter.
I tried the 100 switch back in place and the inverter still wouldn’t connect. The Inverter is supposed to support 1000bps.
It’s an unmanaged switch (TP-Link TL-SG108S). If it’s not raining tomorrow, I might try a different cable direct from the router to the Inverter. Then maybe WiFi - just to pin down what the problem might be.
I’ve also called the installers.
My experience has been both WiFi / Ethernet / Modbus are flakey and it’s taken me a few months to get GivTCP working reasonably reliably. To do that:
(1) Assigned fixed ip addresses in my gateway for both WiFi and ETH connections, eg 192.168.1.10 & .11.
(2) Configured the WiFi connection SSID and pw using the inverter web interface.
(3) Full power-off restart of the inverter, switching off grid and battery isolators.
(4) Unplugging and then reconnecting the ETH to make sure it switched from WiFi > ETH.

Do you find that the WiFi dongle still ‘scans’ for available networks/channels even when connecting via wired Ethernet?
Looking at my gateway there’s been no sign of it connecting. However since I’ve made sure WiFi is configured to connect if it needs to, my daily MODBUS lock ups have stopped. I still get the odd ~10 minutes hangs though.
I don’t have a gateway. I reserved my inverter’s address in the Router for the Ethernet MAC. Haven’t done same for the WiFi MAC though. in fact i don’t think I’ve even connected via WiFi.
Installers came today and couldn’t get connection via Ethernet or WiFi. Coming back tomorrow!
Agree the Comms is flaky. Very poor.
